A team from IBM Research has created the world's smallest magnetic memory bit using only 12 atoms. This is significantly less than today's disk drives which use about 1million atoms to store a single ...

Physicists in Netherlands and Japan are the first to flip the value of a magnetic memory bit by firing a very short pulse of circularly-polarized laser light at it. Unlike other magneto-optic data ...

A quantum-mechanical memory component that might replace the electronic memories used for decades in computers and other gadgets has come closer to practicality, thanks to improvements achieved by ...

In the drive to cram ever more information into handy data-storage devices, researchers have reduced the size of a bit of data to the ultimate limit—a single atom (Nature 2017, DOI: ...

Home > Computing IBM stores binary data on just 12 atoms IBM Research has successfully stored one magnetic bit of data with just 12 atoms of iron, and a full byte of data in 96 atoms. This represents ...

Magnetic media, in the form of disk and tape drives, has been the dominant way of storing bits. But the speed and low power of flash memory has been displacing it from consumer systems, and various ...

Data storage needs to keep up with our desire to snap pictures, download clips from the Internet, and create new digital documents. Since the early stages of computer technology, magnetic storage has ...

Fig.1: Schematic illustration of direct in-situ high-resolution magnetic imaging using MFM. An ultrashort intense laser pulse is guided through a hollow-core fiber and applied to plasmonic structures ...

Data encryption typically relies on the practical difficulty of a process called prime factorization. In this process, a huge number (represented by 1,024 or more bits) is decomposed into a product of ...

Exploiting an ultrashort pulse of laser light to flip the value of a magnetic memory bit could lead to cheap and fast all-optical hard disk drives. Physicists in the Netherlands and Japan are the ...
